For years I've kept a computer file with notes for writing. It contained brief story descriptions, character sketches and interesting lines, some salvaged from failed stories. The file grew to a few thousand lines, with some entries that were years old.
As part of my general decluttering I've now eliminated the file. I've taken out the ideas that suggest viable stories, moved some notes into works-in-progress and the rest are gone. I think that having the file was more of a distraction than an aid. Sometimes things were written in the file rather than take the time to write a fast draft and ended up never being written; other times I wrote things in the file rather than consider them properly at the time.
I'm very excited. I now have a set of short stories that are no longer hidden amongst weeds and rubbish. Over the next few weeks I'll see which ones grow into something interesting. Clutter is never good.
